SHUTTER- 'WORKER.'

SPECIFICATION forming part of Letters Patent 1v 5.'e55,42e, dated August 7, 1900.

Application filed crime 14, 1900.

T0 66 whom it may concern:

Be it known that I, HIRAM K. WrnrcoMB, a citizen of the United States, residing at Everett, in the county of Middlesex and State of Massach usetts,have invented certain new and useful Improvements in Shutter WVorkers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use the same. g

This invention relates to devices for operating window-shutters; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of a portion of a shutter constructed according to this invention. Fig. 2 is a plan view of the bottom hinge. Fig. 3 is a transverse section through the window-sill, showing the working mechanism.

A is the window-sill.

B is a portion of a shutter or blind of any approved construction, and O is a portion of the window-frame.

D is the upper pivot, which is secured to the shutter, and d is an eye secured to the frame C and in which the pivot is free to turn and to slide vertically.

E is the lower pivot, which is secured to the shutter.

F is aplate secured to the window-sill A and provided with a flange f, having notches f in it. A boss e is provided on the plate F, and the pivot E is journaled in the said boss and is also free to. slide vertically in it.

G is a stop which projects from the bottom of the shutter and engages with the notches f of the plate F, so that the shutter can be held in various positions.

A disk H is formed on the pivot E, and I is a bent lever which is pivoted loosely on a vertical pin 2', which projects from the plate F.

A guard h is provided to keep the lever from revolving on its pivot-pin. The short end of the lever projects under the disk H, and the shutter is raised by pressing on the long end of the lever in order to liberate the stop from the notched flange. When the shutter is raised by the lever, it can be swung around Serial No. 20,321. (No modeh) window. The Wheel 76 is arranged in the path of the wheel J, so that the two wheels are placed in gear when the shutter is raised.

M is an operating-handle on the shaft K for revolving it and swinging the shutter around to any desired position when the two beveled toothed wheels are placed in gear with each other.

What I claim is l. The combination,with aframe, and a ver= tically-movable shutter provided with pivots for connecting itto the frame; of a plate secured to the lower part of the frame and pro= vided with a notched flange, a stop on the shutter for engaging with the notches of the said flange, a disk on the lower pivot of the shutter, and a lever pivotally supported by the said plate and projecting under the said disk, whereby the shutter may be raised to free the stop and permit the shutter to be turned on its pivots, substantially as set forth.

2. The combination,with a frame, and avertically-movable shutter provided with pivots for connecting it to the frame; of a shaft journaled in the said frame and provided with an operating-handle and a beveled toothed wheel, a beveled toothed wheel on the lower pivot of the shutter, said Wheels being normally out of gear with each other, and means for raising the shutter, whereby the said wheels are placed in gear with each other, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
